C#websocket服务器接收来自javascript的文本

我目前正在测试一些基本的websocket示例，这些示例对我的基本知识没有完全帮助。我知道如何用C#在服务器上创建一个监听器，并将请求升级为web套接字。我需要帮助检索从javascript发送到服务器的字符串。

C#代码：

class Program
{
    private static void ThreadProc(object obj)
    {
        var client = (TcpClient)obj;
        var address = client.Client.RemoteEndPoint.ToString().Split(':');
        Console.WriteLine(String.Format("A client is connected from {0}", address[0]));
        NetworkStream stream = client.GetStream();
        //enter to an infinite cycle to be able to handle every change in stream
        while (true)
        {
            while (!stream.DataAvailable) ;
            Byte[] bytes = new Byte[client.Available];
            stream.Read(bytes, 0, bytes.Length);
            //translate bytes of request to string
            String data = Encoding.UTF8.GetString(bytes);
            if (new Regex("^GET").IsMatch(data))
            {
                Byte[] response = Encoding.UTF8.GetBytes("HTTP/1.1 101 Switching Protocols" + Environment.NewLine
                    + "Connection: Upgrade" + Environment.NewLine
                    + "Upgrade: websocket" + Environment.NewLine
                    + "Sec-WebSocket-Accept: " + Convert.ToBase64String(
                        SHA1.Create().ComputeHash(
                            Encoding.UTF8.GetBytes(
                                new Regex("Sec-WebSocket-Key: (.*)").Match(data).Groups[1].Value.Trim() + "258EAFA5-E914-47DA-95CA-C5AB0DC85B11"
                            )
                        )
                    ) + Environment.NewLine
                    + Environment.NewLine);
                stream.Write(response, 0, response.Length);
            }
            else
            {
                Console.WriteLine(data);
            }
        }
    }
    static void Main(string[] args)
    {
        TcpListener server = new TcpListener(IPAddress.Parse("127.0.0.1"), 80);
        server.Start();
        Console.WriteLine("Server has started on 127.0.0.1:80.{0}Waiting for a connection...", Environment.NewLine);
        while (true)
        {
            var clientConnection = server.AcceptTcpClient();
            ThreadPool.QueueUserWorkItem(ThreadProc, clientConnection);
        }
    }
}

用于连接到websocket的Javascript。

var host = window.location.origin.replace("http", "ws");
    var socket = new WebSocket("ws://127.0.0.1:80");
    socket.onopen = function (openEvent) {
        console.log("Socket connection is open.");
        sendTextMessage();
    };
    function sendTextMessage() {
        if (socket.readyState != WebSocket.OPEN)
        {
            console.log("Socket is not open for connection.");
            return;
        }
        socket.send("MDN");
    }

更新我现在可以看到消息了。然而，我没有得到字符串MDN，我得到了一些时髦的字符回来。更新了我的C#代码以显示更改。

我只是简单地尝试将javascript中的一个字符串发送到服务器，并在控制台上读取该字符串。如果有人能更多地解释如何同时连接多个网络浏览器，那将是非常棒的。此外，如果有人可以指示我将消息发送回所有连接的网络浏览器，请这样做。

如果这是重复的，请给我指正确的方向。

while(serverIsOn){
    TcpClient cliTemp = server.AcceptTcpClient();
    NetworkStream netTemp = cliTemp.GetStream(); 
    Client cli = new Client(Necessary attributes);
    clientsList.Add(cli);
}

public byte[] javaScriptUser(Byte[] data)
    {
        //encoded[1] => size of msg
        Byte[] encoded = new Byte[((int)data[1] - 128)];
        Array.Copy(data, 6, encoded, 0, encoded.Length);
        Byte[] decoded = new Byte[((int)data[1] - 128)]; 
        //KeyCode positions
        Byte[] key = new Byte[4] { data[2], data[3], data[4], data[5] };
        for (int i = 0; i < encoded.Length; i++)
        {
            decoded[i] = (Byte)(encoded[i] ^ key[i % 4]);
        }
        Array.Copy(decoded, data, decoded.Length);
        return decoded;
    }
